ALEXANDER HALECKI, 0F BARNESBGBO, PENNSYLVANIA.

STEAM-BOILER.

Application filed May 9, 1911.

T 0 all whom it may concern Be it known that I, ALEXANDER T'TALECKI, asubject of the Emperor of Russia, residing at Barnesboro, in the countyof Cambria and State of Pennsylvania, have invented a new and usefulSteam-Boiler, of which the following is a specification.

The invention relates to improvements in steam boilers.

The object of the present invention is to improve the construction ofsteam boilers, and to provide a simple, efficient and comparativelyinexpensive steam boiler, designed principally for use in steam heatingsystems, and adapted to enable hydrocarbon oils, gas and similar fuelsto be advantageously employed, and equipped with means for automaticallyfeeding liquid hydrocarbon to one or more burners, and for deliveringsuch fuel to the burners in a comparatively cool condition.

With these and other objects in view, the invention consists in theconstruction and novel combination of parts hereinafter fully described,illustrated in the accompanying drawings, and pointed out in the claimshereto appended; it being understood that various changes in the form,proportion, size and minor details of construction, within the scope ofthe claims, may be resorted to without departing from the spirit orsacrificing any of the advantages of the invention.

In the drawings :-Figure 1 is a side elevation of a steam boiler,constructed in accordance with this invention. Fig. 2 is an endelevation of the same. Fig. 3 is a transverse sectional view on the line33 of Fig. 1. Fig. 4 is a vertical longitudinal sectional view on theline l-4 of Fig. 2. Fig. 5 is a vertical longitudinal sectional view ofthe boiler, the section being taken through the outer shell.

Like numerals of reference designate corresponding parts in all thefigures of the drawings.

In the accompanying drawings in which is illustrated the preferredembodiment of the invention, the boiler, which is horizontal, comprisesin its construction a main approximately cylindrical shell 1, havingheads or ends 2 and 8 and equipped with an outer curved shell 4c,-surrounding the sides and bottom of the main shell and fitted againstthe latter at the bottom thereof, as clearly shown in Fig. 3 of thedrawings, and spaced from the sides of the main shell to form sideSpecification of Letters Patent.

spaces 5. The outer shell, which terminates short of the top of the mainshell, extends beyond the front and rear ends thereof and is providedwith front and rear walls 6 and 7, spaced from the ends or heads 2 and 3of the main shell to provide end spaces 8 and 9. The side and end spaces5, 8 and 9 are closed at the top by a top wall 10, suitably connectedwith the inner and outer shells.

The main shell is provided with an interiorly arranged combustionchamber 11, consisting of a substantially rectangular boX or casing,extending inwardly from one side of the main shell and terminating shortof the opposite side of the main shell. The combustion chamber is closedat its inner side,

and the main shell is provided at the outer side of the interiorcombustion chamber with an opening 12, and it has a door 13, whichnormally closes the outer side of the combustion chamber. The door 13 isconnected at one end to the main shell by suitable hinges 14, and it isequipped at its other end with a catch 15, engaging with a projectinglug or keeper 16. The door 13 is also provided adjacent to its free endwith a suitable handle 17, and it is adapted to be opened to affordaccess to the interior of the combustion chamber. The adjacent side ofthe outer shell is also provided with a door 18, slightly larger thanthe door 13 and connected at one end to the outer shell by hinges 19,and provided at its other end with a catch 20, engaging a projecting lugor keeper 21. The door 18, which is also provided with a suitable handle22, is adapted to be opened and the door opening of the outer shell isof sutlicient size to permit the door of the inner shell to swingthrough it.

The interior combustion chamber is con nected at its front and rear endswith the end spaces 8 and 9 by short horizontal tubes 23, and the heatfrom lamps 24 passes through the short horizontal tubes 23, as indicatedby the arrows in Fig. l of the drawings, and enters the end spaces 8 and9 and passes therefrom into the side spaces 5, thereby enveloping themajor portion of the inner or outer shell of the boiler and thoroughlysubjecting the water contained therein to the action of the heat.Horizontal partitions or bafiie plates 25 are arranged in the frontportions of the side spaces at a point between the top and bottomthereof for preventing the heat and products of combustion from passingdirectly from the front end spaces 9 into the smoke pipe 26. The smokepipe 26 has an enlarged inner portion 27, extending entirely across therear end of the boiler and closing the rear end spaces 9 at the topthereof, and communicating with the upper portions of the side spaces 5above the hori- Zontal baflie plates or partitions 25 The horizontalbaflle plates or partitions extend inward to approximately the centralportion of the side spaces, and the heat and products of combustion passupward over the horizontal partitions or baflies 25 and escape into theenlarged inner portion of the smoke pipe 26. The upper portion of theboiler is also provided with a plurality of longitudinal tubes 28,piercing the heads or ends 2 and 3 and communicating with the end spaces8 and with the enlarged portion 27 of the smoke pipe to permit a portionof the products of combustion to be drawn through the tubes 28, whichincreases the heating surface of the boiler.

The boiler is provided with suitable supports 29 and is mounted upon asupporting frame 30. The supports 29 space the boiler from the top ofthe bearing frame, which is equipped with an approximately rectangularcasing 31, composed of vertical sides, a horizontal top 32, and acurvedbottom 33, the front end of the casing being open and the rear endof the casing communicating with a fine 34. The top 32 of the casing isprovided with a plurality of openings 35 through which the lamps orheaters 24 extend, the fonts or reservoirs 36 being located within thecasing 31. The lamps or heaters 24 are supported within the upperportion of the casing by holders, consisting of horizontal plates 37 andcoiled springs 38, connected at their lower ends to the plates 37, whichare provided with eyes 39 to reeeive the lower terminals of the springs38. The upper terminals of the springs are secured to eyes 40, whichdepend from the top wall 32 of the casing. The springs maintain thelamps or heaters firmly in contact with the bottom of the boiler.- Thelamps or heaters are provided with suitable burners 41, projecting intoburner receiving tubes 42, which extend from the bottom of the boiler tothe interior chamber 11. The burner receiving tubes pierce the inner andouter shells at the bottom of the boiler, and the bottom of the casingof the inner chamber, and they are suitably secured to the shells and tothe said casings.

The lamps or heaters are supplied with a liquid hydrocarbon or similarfuel by means of tubes 43, connected with the fonts or reservoirs 36 ofthe lamps or heaters and with a tank 44, mounted exteriorly of thecasing and preferably secured to an extension 45 of the top thereof bymeans of suitable hangers or straps 46. The lamps or heaters and thetank are provided with suitable cocks 47 and 48 for controlling the flowof fuel through the tubes 48, which are partially submerged in the watercontained in the lower portion of the casing 31. The bottom portion ofthe casing is constructed to form a water pan 49, and the flue 34 isprovided at the rear end of the casing with an enlarged portion 50 andis connected at its upper portion to the smoke pipe 26, whereby thedraft of the chimney will create a draft through the casing and producean evaporation of the water contained in the water pan 49 andcooperating therewith in maintaining the tubes and the reservoirs of thelamps or heaters in a relatively cool condition. No claim is made in thepresent application to the means for cooling the reservoir and thetubes.

The flue 34 may be provided with a suitable damper for controlling thedraft through the casing 31. The smoke pipe 26 is provided with asuitable damper 51, and it has a circular opening 52 in the bottom ofthe enlarged portion 27 to receive a rotary draft indicating wheel 53.The draft inclicating wheel, which is mounted on a suitably supportedspindle or pivot, is provided with blades and the rapidity of therotation of the wheel 53 will indicate the extent of the draft throughthe smoke pipe. The latter is also provided with a suitable closure 54,pivoted or otherwise secured to the bottom of the smoke pipe andarranged to cover the opening 52. No claim is made in the presentapplication to the draft indicating means. Water is supplied to theboiler through a feed pipe 55, equipped with an automatic float valve56, arranged within the boiler and adapted to maintain the water at apredetermined level. As soon as the water falls below such level, thefloat controlled valve 56 opens and permits the water to flow into theboiler until it is closed by the action of the same.

Although lamps or heaters are illustrated in the accompanying drawingsfor heating the water contained within the boiler, various other heatingmeans may, of course, be employed, and the steam boiler is equipped withan automatic pressure controlling device, which forms the subject-matterof a companion application, filed of even date herewith filed May 9,1911, Serial No. 626,122.

A steam supply pipe 71 is connected with the boiler for supplying steamto the heating system.
